I am US citizen. I am thinking to apply green card for my parents.
I have two questions:
(1) how long does it take to get green card if they are here, and if they are not here?
-About one year, case by case.
(2) My dad has Parkinson's disease. I wonder if he qualifies for green card.
I checked the physical exam for green card, "Classes of Inadmissibility"
defines "People likely to become dependent on need-based government
assistance". He needs my mom to take care of him everyday.
-Irrelevant to your father case at this point and it will not affect his green card approval because your father does not get any government assistance yet.
